Benefits of technology

[0011]According to an aspect of one or more exemplary embodiments of the present disclosure, a coupling strength between the display panel and the panel bottom sheet can be increased, and a restoring force acting on the panel bottom sheet can be reduced. By doing so, the panel bottom sheet may not be separated from the display panel and can perform as designed. In addition, the panel bottom sheet can be tightly coupled with the display panel with no space to be lifted, and thus it is possible to prevent or substantially prevent external foreign matter from penetrating into the display device.

Problems solved by technology

Such organic light-emitting display devices are commonly used in portable electronic devices such as smartphones, and are likely to be subjected to shock.
In addition, if excessive heat is generated in an organic light-emitting element or a driving chip for driving it, the element may be damaged.

Embodiment Construction

[0022]Aspects and features of the present disclosure and methods of accomplishing the same may be understood more readily by reference to the following description of some exemplary embodiments and the accompanying drawings. The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concept of the present disclosure to those skilled in the art.

[0023]Cases in which elements or layers are referred to as being located “on” other elements or layers include cases in which one or more other elements or layers are interposed directly on or between other elements. Meanwhile, cases in which the elements are referred to as being “directly on” indicate that no other element or layer is interposed therebetween. Same reference numerals refer to the same constituent...

Abstract

A display device includes: a display panel including a flat area and a bending area positioned adjacent to the flat area, a panel bottom sheet arranged under the display panel and overlapping with the flat area and the bending area, and a panel-sheet coupling layer between the display panel and the panel bottom sheet and including a first panel-sheet coupling part arranged across the flat area and the bending area, and a second panel-sheet coupling part overlapping with the bending area and extended continuously along a side of the first panel-sheet coupling part, a thickness of the panel-sheet coupling layer becoming smaller from a central portion of the bending area toward a side portion of the bending area, and the panel bottom sheet having a curved shape that is gentler than a curved shape of the display panel.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to and the benefit of Korean Patent Application No. 10-2017-0116555, filed on Sep. 12, 2017 in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference.BACKGROUND1. Field[0002]Aspects of embodiments of the present disclosure relate to a display device.2. Description of the Related Art[0003]Organic light-emitting display devices have advantages, such as good luminance, low driving voltage, fast response speed, and a wide range of color reproduction, and, accordingly, are being employed by a variety of devices including smartphones.[0004]Such organic light-emitting display devices are commonly used in portable electronic devices such as smartphones, and are likely to be subjected to shock. In addition, if excessive heat is generated in an organic light-emitting element or a driving chip for driving it, the element may be damaged. In order to protect the eleme...
